Fix PowerBroker Identity Service (formerly Likewise) on CentOS 7

pbis_centos7.txt

PBIS (PowerBroker Identity Service) throws some errors while installing v8.2.2 (latest as of 25 June 2015) rpm.

[root@centos7 ~]# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
[root@centos7 ~]# ./pbis-open-8.2.2.2993.linux.x86_64.rpm.sh install  (This is filtered output)
...
...
Error: /usr/bin/systemctl enable /etc/pbis/redhat/lwsmd.service returned 1
Failed to issue method call: Unit /etc/pbis/redhat/lwsmd.service does not exist.

Error: /sbin/service lwsmd start returned 6

[root@centos7 ~]#

To rectify the errors, run the below commands and reboot the server.
[root@centos7 ~]# ln -s /etc/pbis/redhat/lwsmd.service /etc/systemd/system/lwsmd.service
[root@centos7 ~]# cp /etc/pbis/redhat/lwsmd.service /lib/systemd/system/lwsmd.service
[root@centos7 ~]# systemctl enable lwsmd.service

You are right, 8.3.0-3287 is the latest now. However, 8.2.2-2993 was the latest available through the shell script (encapsulated with rpms) that day.

Anyways, can you try runnning 'systemctl enable lwsmd' ? I still get that error in both the versionswith the shell script and the repo (which is obvious) as well. I had updated systemd in both cases.

This is not alarming, but the below command gives me an option to enable the service after disabling it which I believe is important for me.

[root@centos7 ~]# cp /etc/pbis/redhat/lwsmd.service /lib/systemd/system/lwsmd.service

Check this.

[root@centos7 ~]# yum install pbis-open
[root@centos7 ~]# systemctl status lwsmd  (running, I have removed the output)
[root@centos7 ~]# systemctl stop lwsmd
[root@centos7 ~]# systemctl status lwsmd  (stopped, I have removed the output)
[root@centos7 ~]# systemctl enable lwsmd.service
Failed to issue method call: No such file or directory
[root@centos7 ~]# systemctl disable lwsmd.service
rm '/etc/systemd/system/multi-user.target.wants/lwsmd.service'
rm '/etc/systemd/system/nss-lookup.target.wants/lwsmd.service'
rm '/etc/systemd/system/lwsmd.service'
[root@centos7 ~]# systemctl enable lwsmd.service
Failed to issue method call: No such file or directory
[root@centos7 ~]# systemctl status lwsmd
lwsmd.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

[root@centos7 ~]#

Overall, this is the process one should follow on CentOS 7.

yum update systemd

yum install pbis-open
or
./pbis-open-8.*.linux.x86_64.rpm.sh install

cp /etc/pbis/redhat/lwsmd.service /lib/systemd/system/lwsmd.service

After this these commands behave as they should.

[root@centos7 ~]# systemctl status lwsmd  (running, I have removed the output)
[root@centos7 ~]# systemctl stop lwsmd
[root@centos7 ~]# systemctl status lwsmd  (stopped, I have removed the output)
[root@centos7 ~]# systemctl disable lwsmd.service
rm '/etc/systemd/system/multi-user.target.wants/lwsmd.service'
rm '/etc/systemd/system/nss-lookup.target.wants/lwsmd.service'
rm '/etc/systemd/system/lwsmd.service'
[root@centos7 ~]# systemctl enable lwsmd.service
ln -s '/usr/lib/systemd/system/lwsmd.service' '/etc/systemd/system/multi-user.target.wants/lwsmd.service'
ln -s '/usr/lib/systemd/system/lwsmd.service' '/etc/systemd/system/nss-lookup.target.wants/lwsmd.service'
[root@centos7 ~]# systemctl start lwsmd
[root@centos7 ~]# systemctl status lwsmd  (running, I have removed the output)
